i LACING-HOOK-SETTING MACINE.

Application filed september 9, i907. serial no. 391,940.'

.. and useful Improvements in Laci-iig-llook Setting .\lachines, of which thel following is a specilication. This iniv'ention relates to machines for setting lacing hooks and the like in sheet. material such as the uppers of boots and shoes and relates particularly to the punch and die by means of which the upper is perforated and fed into position tohave a lacing hook Set therein. i Y

'liile I have in the following specification described my device as particulai'l adapted to the setting of the lacingr Ahooks in the up-l pers of boots and shoes, it is evident that the same may be used for setting other articles in sheet material, as', for instance, the same may be used for setting eyelets in the uppers of boots and shoes. i

The device of mv invention is particularly adapted to that class of machines in which the acing hooks are set in the upper and the upper fed automatically by t-he machine, and the device of this invention is an im )rovementl upon the machine for setting acing hooks invented by Sydney E. Taft for which he obtained U. S. Letters Patent No. 883,256, dated A\lar. 31, 1908. In machines of the class to which this invention relates the machine is run at a very high rate of speed and the feeding of the u )per especially inuppeis of thin, flexible leatlier becomes a matter of great difficulty. In the present invention the unch is adapted to be moved downwardly through the upper until the lower end of said punch projects downwardly into a hole which surrounds and fits said punch and is formed in a female die. After the punch has perforated the upper and descended, as hereinbefore set forth, below the under surface of the upper the mechanism is so arranged as to move the punch upwardly until the lower end of the punch just clears the bot,- tom of a groove which is formed in the top of the die and leads out of one side of the hole in the die, said groove being of less depth than that of said hole. T he lower end of the iunch,

lit will be understood, at this time sti l projects through the upper, the mechanism is hen adapted to move the punch laterally Specification of Letters Patent. 'v

v*I Patented Sept. 22, 1908. i

i while the lower end ofthe punch projects into the groove in the female diei-and below the lower surface of the material which it has perforated. The lateral movement of the punch, ashereinafter more. fully described, moves the leather forward until the punch is in alinement with a lacing hook to be set therein held upon a suit-able carrier or driver and the setting operation then takes place, the punch during the setting operation still projecting below the under surface of the u er, thus forming a guide for the stem of t e acing hook when it first -enteis the upper, Y

and guiding the same accurately into the hole formed by the punch. The mechanism by means of which the punch and anvil are operated as well as the lacing hook carrier may be the same as that illustrated in said Letters Patent-to which reference may be had for the details of mechanism for o perat-` ing the punch, die and setting mechanism.

Referring to the drawings: Figure 1 isa. plan view of my improved die. F 1g. 2 1s a sectional elevation taken on line 2-2, Fig. l.

Fig. 3 is a sectional elevation taken through the center of the die illustrating the relative osition of the punch, anvil and die to the lacing hook carrier and to the work support, a presser foot also being shown in connection therewith, the parts being in the position occupied thereby when the punch has perforated tlie up )er and before the feeding operation takes place. Fig. 4 is a view similar to Fig. 3 showing the punch partly retracted from the upper and from the die in readiness to be moved laterally to feed the upper into position to have a lacing hook set therein, a lacing hook being also shown in position upon the carrier. Fig. 5 is a Vsectional elevation similarto Fig. 3 illustrating the parts in the position assumed thereby when the lacing hook has been set. Fig. 6 is a transverse section taken on line 6-6, Fig. 3, and shown partly in elevation.

Like numerals refer to like parts through-A able mechanism being supplied to move the` 6, inclusive.

I die holder-and the die attached thereto in the Aopposite direction to that in which it is moved by the spring 16. The lacing hook 1S is held upon a carrier 19 to which a vertical reci rocatory motion is imparted by suitable i- -niec ianisni. woik support in a stationary position, when The upper is held upon the so desired, b v a presser vfoot 2O which is moved toward or away from the upper by suitablemechanism at the proper time. Y An anvil 21 against which the lacing hook is clenched is provided with a projection 22 constituting a punch.. All of said parts are substantially the same as shown and described in the said Letters Patent with the exception of the die 13.

bottom of the die, as illustrated in Figs. 1 to A groove 24 is provided in the upper surface of the die which leads out of one side of the hole 23 and is continued to the work support 10 and die 13 and the punch is moved downwardly perforating the upper and descending until the lower end of the punch passes through the upper and into the iole 23 in the die 13, the piece of leather 26 punched from the upper being pushed downwardly into the hole 23.' The iuncli and die are then moved laterally to a out the position illustrated in Fig. 4 and during the last part of said lateral movement the punch is raised to the position illustrated in Fig. 4, that is, with the lower end of said punch just clearing the bottom of the groove 24.' 1When the holder 12 comes to a stop together with the die 13 fast thereto, the punch and anvil continue the lateral movement in the direction of the arrow, Fig. 4, and the upper is fed forward until the punch 22 alines with the lacing hook 18 held upon the carrier 19, said carrier is then brought upwardly and theV punch, .the lower end of which is projecting through the upper and downwardly therebeneath, acts as a guidefor the neck of t-lie lacing hook which isthus guided through the hole made by the punch in the upper and clenched against the anvil 21, as illustrated in Fig. 5.

It is evident that if desired the movement of the beider 12 may be dispensed with and the die be made stationary, in which case the unchlng of the upper would take place as iez'einhefore described, but the die would remain staiona-r at all times while the upper Said die has a hole 23 therein 'which preferably extends from the top to the ject through'the upper, as liereinbefore dethcfecdin'goperations. lt will be seen that' upper -canrenuiin at all times resting upon feeding operation no niat-ter'how-"thin or it will be notie tli'attheupper is always held in the sanicfhorizontal plane bothbefoic, during and after the feeding operation.- As

operation of punching, feeding the upper, and setting the lacing hook in the u ier, is repeat-ed until'the required number ofiillacing hooks has been set in the upper, whenthe machine is stopped and the upper removed by the operator.
